IBOTTLE-CAPPING MAGHI E.

To all whom it may concern:

Be it known that I, JOHN J. GAYNOR, a citizen of the United States, and aresident of Indianapolis, county of Marion, and State of Indiana,have invented a certain new and useful Bottle-Capping Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the. accompanying drawings, in which like letters refer to like parts.

7 The object of this invention is to improve the construction of bottle capping machines, so as to reduce materially the. compression required and, therefore, the breakage of bottles, and materially lessen the power re- 'quired to operate the machine and also to reduce the wear of the throat of the capping mechanism. 7 p

One feature of the invention consists in providing adjustable means in the bottle support for yieldingly resisting the down-' ward movement of the bottle support so as to prevent the same from injuring and crushing the bottle, and means accessible through the upper portionof the bottle support for adjusting said means. This enables said means to be adjusted without thefremoval of the casing surrounding the bottle support,

as heretofore.

1 Another feature of the invention consists in centrallylocated means for resistingthe downward movement of the bottle support, said means extending centrally through a plate supportedby a sleeve carried bythe main spring, whereby said spring tends to hold the means for resisting the downward movement of the bottle support frictionally in place and the tension of said spring can be readily adjusted by the means above mentioned. Along with the, foregoing is the idea of having the'means for operating the dog for resisting the downward movement of the bottle support centrally: of the bottle.

support.

The full' nature of the invention; will; be i 1 understood from the I accompanying draw- .ings and the following description and claims. i

the same with parts shown inposition after having yielded to the downward movement' i of the bottle support. Fig. '3is a section on the line, 33 of Fig.1; Fig. 4 is a sec tion on the line 44 of. Fig. 1. Fig. 5., is a section on the line 5-5 of Fig. 1. Fig. 6 is a section on they line 6.6 of Fig. 5.

. The crowning head mechanism for applying the crowns to the bottles is not here shown. as the same is familiar to those skilled in the art, and likewise a tubular casing in which the bottle support is mounted isomitted andalso the means forvertically actuating the bottle support. i

The'bottle support 15 supports the bottle and forces it up .against the cap and cap plate, "not shown- The bottle support at its lower end extends into'a tube 41 which. is vertically movable by means not shown. The bottlez support is supported yieldingly on said tube 41 by a spring 47 so that as the tube 41 is elevated, the bottle support will be yieldingly elevated for forcing the bottle up into the mouth of the crowning plate. Thespring 47 surrounds a lip sleeve 50 vwhich surroundsthe middle portion of the bottle support, as shown in Fig. 1, and upon which a plate 51 lies of the shape shown in Fig. -3,the reduced portion thereof operating vertically in a slot 52 in the bottle support, and a wider portion thereof operating vertically ina wider slot 53 in the bottle support.

Thepurpose of the plate 51is themounting therein of a threaded rod 55 which screws through the head of a connecting rod 56 which extends down beside and below a cross bar; 57 and engages a projection 58 on the upper end of a dog acts against the plate51 and throughvthe 59. The spring 47 .v Y

means just described holds the upper end of the dog 59 against the'bottom of the cross bar 57. .Said cross bar is secured .to

and the, action of the spring 47 through said 60 secured to the inner surface of the tube41.

the lower portionof the bottle support 15 95. meanstends to hold the lower beveled end of the dog upon the beveled end of a plate The friction between the beveled ends of the parts 59 and 60 causes the upward movement of the bottle support along with the upward movement of the tube 41 unless the strain becomes so great on the bottle that 1t might break and then the resistance of the spring 47 and the friction between the parts '59 and 60 is Overcome sufiiciently to permit the beveled end of the dog 59 to escape from the beveled end of the plate 60 and then the tube 41 is permitted to move farther upward without any corresponding upward movement of the bottle support, as shown in Fig. 2. As soon as the strain'has ceased, the dog 59 will be forced back into the position shown in Fig. 1 by the spring 47 The degree ofresistance eflected by the inclined face of the dog 59 and of the spring 47 is adjusted by a nut 62 on the rod 55 and said nut is rendered accessible to a wrench insertible through a hole 63 extending centrally through the upper part of the bottle support and closed by a screw plug 64 in the upper end of the bottle support and which is readily removable. Heretofore, to effect similar adjustment, it has been necessary to remove the outer casing not shown in order for the adjusting means to be accessible. With the present improve-, ment, this becomes unnecessary as the plug 64 can be readily taken out and the adjusttherod 55 centrally of the ment effected from above. The spring 47, as seen, performs three functions. It forms a yielding resistance between the bottle support 15 and the tube 41 and it also controls the degree of frictional resistance between the dog 59 and the plate 60 and returns said dog to its normal position. By arranging plate 51 and mounting the dog 59 centrally of the tube 41 and connecting them as above described, a center pull is obtained which maintains the parts in balanced condition during the operation of the device.

The invention claimed is: j

1. A bottle capping machine including a tubular bottle support, an elevating member on which it is mounted, yielding resistance between said members, means accessible through the top of said bottle support for adjusting said resisting means, and a removable plug in the upper end of the bottle support for closing the openingtherethrough and providing a bottom'support for the bottles.

2. A bottle capping machine including a tubular bottle support, an elevating member on which it is mounted, a spring surrounding said bottle support and bearing against said elevating means, a plate extending through the bottle support at the other end of the spring, and centrally located means in the bottle support for adjusting the tension of the spring and accessible through the top of the bottle support for its adjustment.

3. A bottle capping machine including a tubular bottle support, an elevating member on which it is mounted, aspri'ng surrounding said bottle support and bearing against said elevating means, a fixed beveled plate on said elevating means, a dog with a beveled end engaging said beveled plate and its other end engaging said bottle support, and means centrally located within the bottle support and spring for transmitting the action of the spring to said dog for holding it normally in engagement with said plate.
